Feasibility - percentage of patients recruited from those approached, percentage of patients who dropped off, percentage of patients who are compliant (attending more than 75% of recommended sessions) [ Time Frame: While receiving chemotherapy (usually 4-5 months) ] [ Designated as safety issue: No ]

Fatigue will be measured by the before the start of chemotherapy, monthly while receiving chemotherapy (usually 4-5 months) and at 3 months after chemotherapy

Quality of life measured by the Functional Assessment of Cancer Therapy - Breast - statistically and clinically significant improvement in quality of life [ Time Frame: 7-8 months ] [ Designated as safety issue: No ]

There is evidence that mindfulness-based interventions (MBIs) such as meditation, mindfulness-based stress reduction (MBSR) and yoga might improve Quality of Life (QOL) and reduce stress in breast cancer survivors. These interventions are becoming increasingly popular in cancer survivors. However, little is known about the feasibility and effect of MBIs administered during the interval of time of chemotherapy, on QOL and stress. The investigators are planning a MBI intervention study developed specifically for breast cancer survivors receiving chemotherapy (usually 4-5 months) at the investigators institution, for at least 8 sessions combined with at least 8 weeks of home-practice, in 25 women receiving chemotherapy for breast cancer.
